I/O

Function

I/O These pins comprise 16-bit bi-directional data.

When the serial interface has been selected (PSX = L), D7 functions as

a serial data input pin (SI), D6 functions as a serial clock input pin (SCL).

In either case, pins D0 to D7 and D8 to D15 are in high impedance mode.

When the chip is not selected, D0 to D15 are in high impedance mode.

Input

When parallel data transfer has been selected, this pin is usually

connected to the least significant bit of the standard CPU address bus

and is used to distinguish between data from index registers and

data/commands.

RS = H: Indicates that data from D0 to D15 is data/command

RS = L: Indicates that data from D0 to D7 is index register contents

Also, when serial data transfer is selected, the level of the RS pin is

fetched at the rising edge of the eighth clock of the serial clock and

whether the data is index register contents or data/command is

distinguished.

RS = H: Indicates that the data input to SI is data/command.

RS = L: Indicates that the data input to SI is index register contents.

Input

This is a general-purpose input port. The status of these pins (H or L)

can be read via a command.

Because this is a CMOS input, do not leave open.

Output

This is a general-purpose output port. The status of these pins (H or L)

can be write via a command.

Leave open when in unused.

Input

This pin is for oscillation signal selection. When in used external

resistance connection oscillator circuit, this pin set H. When in used

internal oscillator circuit, this pin set L.

RSEL = H: External resistance connection oscillator circuit select

RSEL = L: CR internal oscillator circuit select

Input This pin is for oscillation signal input.

RSEL = H: Connect 51 kΩ resistance between OSCIN and OSCOUT.

RSEL = L: Leave open

Output This pin is for oscillation signal input.

RSEL = H: Connect 51 kΩ resistance between OSCIN and OSCOUT.

Output

RSEL = L: Leave open

This pin outputs STB signal for gate driver leveled by interface power

supply voltage (VCC2). This output signal is reverse signal of GSTB.
